Go on this video and starting at 4:48 we see a brand new location on Earth. (From what I can tell.) Then shortly after a new crucible map on one of Mars' moons and something like a dragons skeleton (Rib cage) on a place on what I can guess to be the Moon. I call this DLC because they showed the footage after mentioning the 2 dlc packs and how they'll expand Destiny. It seems to be from before the golden age (more present day) and i'm pumped.
Edit: We can see a flag and banner on the left that might tell us something about the location.

The cylinder of light is most likely inside the Citadel, but I could be wrong. However, the other locations, such as the one on Earth, the Moon map we haven't seen footage of yet, the ribcage, and the Mars footage, may be in the expansions.
